Multiple antennas and interruption time values for sounding reference signal (SRS) switching
A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications.

Buffer assignment balancing in a network device
Techniques for improved handling of queues of data units are described, such as queues of buffered data units of differing types and/or sources within a switch or other network device. When the size of a queue surpasses the state entry threshold for a certain state, the queue is said to be in the certain state. While in the certain state, data units assigned to the queue may be handled differently in some respect, such as being marked or being dropped without further processing. The queue remains in this certain state until its size falls below the state release threshold for the state.

Dynamic selection of router groups to manage computing instances
This disclosure describes techniques implemented partly by a service provider network for dynamically selecting between router groups to account for scaling up and/or scaling down of managed instances that are serving concurrent requests. Router groups define bandwidth allowances for routers that restrict the number of machine instances the routers are allowed to manage for individual user accounts. As concurrency of requests increases for a user account, rather than using more routers in a router group with a smaller bandwidth allowance, the techniques described herein include selecting a different router group for the user account that defines larger bandwidth allowances for user accounts. The service provider network may determine that the number of concurrent requests for a user account has passed a threshold for a router group, and select a new router group for routing new requests and managing containers of instances that are processing the existing concurrent requests. |

Direct-to-user Earth observation satellite system
Satellites in the direct-to-user Earth observation (EO) satellite system support inter-satellite communication and form a multihop communication network. Each satellite has a radio transceiver with a phased array antenna for directly communicating with a user radio station that issues an EO request of a user. Physical servers are distributed over the satellites and networked to form an in-space computer network that is Internet-enabled. The multihop communication network enables the servers to be mutually communicable. Raw data generated from the EO sensors are processed by the servers to yield desired EO data that meets the user's requirement. Advantageously, the servers set up a user authentication server configured to verify the user identity for determining acceptance or denial of the EO request, and an application server for interacting with the user. Hence, the EO request is entirely handled in Space without involving a terrestrial non-user facility for user authentication and raw-data processing. |

System and method for communicating via a satellite in an inclined geosynchronous orbit
A hub terminal and remote client communicate via a target satellite in an inclined geosynchronous orbit. As the target satellite ascends or descends away from the geostationary arc, the signal strength of the uplink channel is increased without increasing the level of interference with adjacent geostationary satellites. The increased angular separation from adjacent satellites also decreases downlink interference. The resulting increase in signal to interference ratio permits adjustment of the modulation and coding parameters to increase spectral efficiency. The antenna gain pattern is modeled based on antenna characteristics and the model may be supplemented with measurements of a signal relayed by adjacent satellites. The method permits intermittent communication from locations where the geostationary arc is blocked or using disadvantaged antennas that would be impractical for use with geostationary satellites. In some circumstances, it is desirable to deliberately mis-steer the antenna slightly away from the target satellite. |

Gate cut with high selectivity to preserve interlevel dielectric layer
A method for preserving interlevel dielectric in a gate cut region includes recessing a dielectric fill to expose cap layers of gate structures formed in a device region and in a cut region and forming a liner in the recess on top of the recessed dielectric fill. The liner includes a material to provide etch selectivity to protect the dielectric fill. The gate structures in the cut region are recessed to form a gate recess using the liner to protect the dielectric fill from etching. A gate material is removed from within the gate structure using the liner to protect the dielectric fill from etching. A dielectric gap fill is formed to replace the gate material and to fill the gate recess in the cut region. |

Method of correlating precursor and fragment ions using ion mobility and mass to charge ratio
A method of mass spectrometry is disclosed comprising separating precursor ions using an ion mobility separator such that different precursor ions have different drift times through the on mobility separator; mass filtering said separated precursor ions with a mass filter, wherein the mass to charge ratios of the precursor ions transmitted by the mass filter vary as a function of the drift times of the precursor ions through the ion mobility separator; performing a first mode of operation comprising fragmenting the separated and mass filtered precursor ions in a fragmentation device to form fragment ions; urging the fragment ions through the fragmentation device such that fragment ions derived from different precursor ions that have been separated by the ion mobility separator are maintained spatially separated from each other as they are urged through the fragmentation device; and detecting the fragment ions. The method enables precursor ions to be associated with their related fragment ions more accurately. |

Microscopy imaging method and system
Notches or chevrons with known angles relative to each other are formed on a surface of the sample, where each branch of a chevron appears in a cross-sectional face of the sample as a distinct structure. Therefore, when imaging the cross-section face during the cross-sectioning operation, the distance between the identified structures allows unique identification of the position of the cross-section plane along the Z axis. Then a direct measurement of the actual position of each slice can be calculated, allowing for dynamic repositioning to account for drift in the plane of the sample and also dynamic adjustment of the forward advancement rate of the FIB to account for variations in the sample, microscope, microscope environment, etc. that contributes to drift. An additional result of this approach is the ability to dynamically calculate the actual thickness of each acquired slice as it is acquired. |

Left-right canted-cosine-theta magnets
Disclosed herein are superconducting gantry magnets that include multiple quadrupole winding sections placed in sequence on a curve such that the effective current direction is reversed between sections. This produces alternating quadrupole field regions along the length of the bend whose individual integral strengths can be tuned by the location of the current polarity transitions. A simple transition scheme to reverse the current between sections can be implemented to allow for the use of one continuous winding and power supply. Dipole windings can be included in the superconducting gantry magnets so that the magnets produce superposed dipole and alternating quadrupole fields. The disclosed design for the windings and transition scheme to reverse current polarity can be implemented for higher order multipoles as well. |
